<pre>
For similar polygons, the ratio of the lengths of their corresponding sides is the same as the ratio of their perimeters.


Therefore, you have this PROPORTION:


{{{x/3}}} = {{{192/36}}}.


It gives you  x = {{{(192*3)/36}}} = 16.


<U>Answer</U>.  The length of the corresponding side in polygon R is 16 cm.
